The XTX radiator will utilize*three*Nidec-Servo*Scythe Gentle Typhoons (Model# D122C). This fan has been regarded as the best static pressure optimized fan by DIY PC community since it's release in 2008. The original D122C is no longer made, but there is limited stock available at some online retailers. Last year the D122C Scythe GT fan was resurrected and manufactured as "Darkside Black Edition" by Dazmode. It's the same specs as the original, but now has Black fan blades. Many PC Modders including myself have painted these fans to fit the color schemes of our custom PC builds. I've been asked several times over the years how to remove the c-clip without losing or breaking it? Like many others, I've also lost these tiny c-clips while learning the best technique for removal. This is my DIY guide to removing and installing external retaining ring or c-clip.

WARNING:
Perform this task with Safety Glasses, the tiny Black metal retaining ring (c-clip) can and likely will pop off, so perform this task in a clean workspace, so you can find it. I suggest doing the work on a large white bed sheet and holding a large magnet near the fan hub as you remove and re-install the c-clip, to increase you're chances of not losing the c-clip. I haven't found a source for ordering replacement c-clips yet, but I'm still searching.
Here is my suggested Tools & Supplies
Safety Glasses (not pictured)
Heat Gun for removing the fan label. Hair Dryer on HIGH setting will work as well.
10" Wire Cable Tie
Large magnet (not pictured)
External Fixed-Tip Retaining Ring PliersTweezers
Needle Nose Pliers

http://www.saeproducts.com/retaining-ring-tool.htmlThe fan blade looks as if it would snap-on and off, but not the case.
We need to remove the back label to access the external metal c-clip on the fan shaft.
Swipe heat gun or hair dryer back and forth over the label.
Use the Tweezer to peel off the fan label.
Stick the fan label on a clean metal surface while you perform your work.
You will tie down the fan hub with this Twisty tie. The fan shaft has a retention spring inside. You need to compress this spring, so you can remove the metal c-clip. If you don't, it's almost a guarantee that the c-clip will fly off the shaft faster than a bullet.

Insert the two prongs of the Retaining Ring Plier inside the jaw of the c-clip.
If you have a large Magnet, Position it near the fan hub, just in case the c-clip pops off.

You will widen the jaw of the c-clip and need to bend it back to it's original opening, so it maintains it's grip.
Hold the c-clip in the Tweezer while using a Needle Nose Plier to compress jaw of the c-clip.
I debated about which color to paint the Scythe GTs for EK's 360 XTX Radiator. Decided to leave the fan blade hubs their factory grey and paint the frames GULF Blue, which works together and helps break up all of the orange.
